IMPROVEMENT iN THBMANUFAGTURB or Bossu-COLLARS.

To ALL WHoMi'r. MAY CoM-CERN:

Bc it known that I, E. P. EDSTROM, of Somerville, in the county of Middlesex, and State ott' Massachusetts,

have invented certain new and useful improvements in the Manufacture of Horse-Collars and I do hereby declare that the following, taken in connection with the drawings which' accompany and form part of this specification, is a descriptlon of invention suiiicieut to enable those skilled in the art to practise it.

The invention.- rela-testo the construction of horse-collars, and particularly. tofthe manner of forming the roll or rim, which, irl-"connection with the body, formsithe bed and groove for the application of thehames'. In the comui'on construction` of horse-collars it ispeustomary to first form4 the outer material or covering' of nthe roll into a tube, and to'then stuil suoli tube'with a filling of straw'orother 4similar material. Such .construction is for many reasons objectionable, and I have of late devised, -to take the place thereof, aroll which acore is rstuform'ed of the general shape of the collar, 'over which core,` the ilcathicrit-oformst'hcroll isf vdrawn and stitched, and it is in such method or process of .forming the 'oll thatr my present invention consists.

In carrying out my invention I prefer to employl a series' of blocks, such as are shown in the drawings, my method of 'procedure'being as follows: y

I irst take a piece of rattan, or other suitable flexible or sonewhat fiexible and elastic material, and, havi ing eut it to the proper length andreduced it to `thcpropcr thickness and form, as seen at a, Ishavc down the l ends, and fasten upon them strips of leather-b, and then bend thc core-piece -and secure the two cnd's'of'leather together, as seen at c.' The piece d, which is in a wet or 4somewhat soft condition, I then Vplaee'upon the block A, said block having a bed-face, d, against which the: piece a lies, and n. former', e, of the general outline or shape which itis desired that the collar may have. The point-piecef of the former slides outwardly in the block, and the pieeea, being laid around the former 'as seen at A., a wedge is driven between the piece f and the main former-block e, till the wood or other materialV a lies closely against the 'edge of the pattern-block e all along its length, in which position it is left. vto dry.' Being then removed, this piec'elretains ts shape, and forms the core upon which the roll is to he formed. A face v icw of' the core upon the former-block is shown .at A, and a cross-section of the core and block at B lI next take this core and stretch it upon the block Cl.

This blockA alsoA is made in two parts, in the edge of which is sunk a groove, g, as seen at D, which lshows a section of the block andcore, and the core being slipped upon the block andinto thegroove, the pieces L 2' are wedged apart to strain the core upon the block to hold it firmly in place; Through a hole, lc, I clamp the bloei;

to the side of a bench in upright position, or so that I'may rotate it' upon the screw or clamp-pin. I thon stretch over the .outer surfaceof thev core` the central part of a strip of leather, which is to forni a lining to ithe outer or face-leather of the roll, this lining being first laid over the core, and the face-leather over it.

Having the lining-leather wet, and while in a pliant condition, I tack one end of it to the top of the core,

and stretch it gradually over the outersurface of' the core, turning thc block as I proceed, so that when the core is removed from the block, and the lining is drawn, around it, the outer part of the strip shall be so 4stretched that the .part which goes within the core shalt not puck-er. This being effected, I stretch over4 this lining-leather the outer leather in the samemanner, and for the same purpose of making it lie smoothly upon the inner as well as on the outer surface of the core when finished. Previously to such manipulation these pieces are cut to the proper length, and of a width suiiicient to leave opposite projecting edges upon each when they are applied 4to the core, something as seen at E, the edges of the lining piece projecting out beyond the edge of the faceleather,'which is eut narrower than the lining. In this position they are basted together, the thread running through the four edges. The roll s o covered, I layupon a third block,-F, `seen in section at G, and stitch to it the body-leather Z, the face side of which at the inner edge is laid against the inner oncof the edges `of the Aroll-leather previously hasted together, and the veiare then stitched tightly together, during which operation the shape of the block allows the wide body-leather to fall down into its hollow m, so as to leave:T free room for the stitching, and for the body-leather to be laid smoothly along the roll, which would not be theV case were the roll placed on a bench, held in the lap, or plaeed'on the door. The inner body-leather having been ythus-applied, itis turned over, the outer piece is connected to it, andthe body is stuffed in the usual manner.

In the manufacture of key-collars, or that lclass of' collars in whielithe part of the body within the collar is extended over and so as to form part of the roll, I stitch this body-piece and the outer rim or face-piece together before placing them oir-the roll, and I then' apply the collmgwith the inner or lining` part applied thereto, to a. block, H, having :L Wide groove, u, and draw on land secure the outer covering -While the collar is upon such block II, the width of the groove 1L permitting the inner surface of the roll and body tol itA therein, endthis block H Vbeing used as an auxiliary to the other blocks.

I claim the improvement-iu'the manufacture o f liorse-eollu'rfs/by forrningpsJh core, und applying thereto the gell Aand body-leather upon n system or series of blocks,,substantially ae set forth.
